Description

Partitioned heat supply type cooking equipment containing graphene

Technical Field

The utility model relates to the technical field of kitchen electric equipment, in particular to partitioned heating type cooking equipment containing graphene.

Background

With the comprehensive development of technologies related to the field of home appliances, home appliances have been developed in both of the rich and refined aspects. Kitchen electric appliances are one of the household appliances, and are mainly cooking appliances for preserving and processing food materials, and along with the development of enrichment and refinement, specific forms corresponding to various cooking modes such as steaming, baking, frying, air frying and the like are developed in addition to traditional gas cookers, refrigerators, microwave ovens and the like.

Taking an oven as an example, the working principle of the oven is to cook food materials by using circulated hot air flow. Specifically, along with the circulation flow of the hot air flow in the inner container where the food to be cooked is located, when the hot air flow flows through the food, the heat carried in the hot air flow can be transferred to the surface of the food, and parameters such as the flow rate and the temperature of the hot air flow are correspondingly controlled.

In order to heat the hot air flow better, a heating component is added. Such as by placing additional heating coils in the top, bottom, etc. of the oven. Since graphene has excellent thermal and electrical conductivity, a heating structure including graphene has better heating performance than a general heating coil. However, since graphene has a very high hardness, there is a problem in that it cannot be bent when it is processed into a tubular structure.

As an improvement, there is the following processing mode:

as disclosed in chinese patent (CN 212546594U), a heating structure and a steaming oven are disclosed, wherein the heating structure is configured to be disposed in a cavity of the steaming oven, the heating structure includes a lower heating element, the lower heating element is configured to be disposed at a bottom of the cavity, the lower heating element includes a thick film heating plate and a first graphene heating plate, and the first graphene heating plate is disposed around the thick film heating plate. When the first graphene heating plate is electrified to heat, the first graphene heating plate heats food in a heat radiation mode, and the heating efficiency is high.

It can be seen that, in this document, the area of heat radiation is ensured by the extended plate-like structure, the layout mode of the heating plate is not flexible enough and there is a strong correlation between the layout mode and the material of graphene.

As another example, chinese patent (CN 215305077U) discloses a steaming and baking oven, including a water-containing tray body and a box body for enclosing into a cooking cavity, in one embodiment, the position of the water-containing tray body, on which the first insulating layer is printed, is printed with the second insulating layer, the graphene heating wire is packaged between the first insulating layer and the second insulating layer, specifically, the position of the water-containing tray body, on which the first insulating layer is printed, is printed with the second insulating layer, the graphene heating wire is packaged between the first insulating layer and the second insulating layer, the heat generated by electrifying the graphene heating wire can be easily transferred to the water-containing tray body through the second insulating layer, the heat loss is small, and the heating efficiency is high.

It can be seen that in this document, the process of packaging by printing an insulating layer on a graphene heating wire is based on the graphene heating wire, and the insulating layer printed thereon serves as an insulating function and an auxiliary function. Therefore, in this document, the layout manner of graphene is still strongly related to the material of graphene.

Accordingly, there is a need in the art for a new solution to the above-mentioned problems.

The present utility model has been made to solve the above-mentioned problems, at least to some extent.

Technical proposal

In view of this, a first aspect of the present utility model provides a partitioned heat supply type cooking apparatus including graphene, the cooking apparatus comprising: 1) A cooking body formed with a cooking chamber in which food to be cooked can be placed; and 2) a graphene heating portion comprising a plurality of graphene heating units, the graphene heating units comprising a carrier portion comprising a first carrier disposed at the cooking body; wherein at least a portion of the first carrier is coated with graphene to form a graphene coating; wherein at least two of the plurality of graphene heating units are disposed at different positions of the cooking body so as to: the graphene heating part radiates heat to a cooking medium for cooking food materials to be cooked in a distinguishable manner.

With such a configuration, the graphene heating portion can be disposed on the cooking body in a more flexible manner.

Specifically, the material of the carrier portion of graphene, which is a heating effective material, is not necessarily a graphene structure, and thus the shape thereof is not limited by the hardness of graphene. On the premise, the structure can be changed according to actual requirements and can be flexibly arranged at the corresponding position of the cooking main body. For example, the cooking device can be processed into structures such as plate-shaped structures, tubular structures, special-shaped structures and the like according to actual requirements, and is arranged in a local area or all areas of the cooking main body, and specific positions for arrangement are selected.

On the premise of ensuring the functions, the person skilled in the art can select the material of the carrier part and the specific structural form of the carrier part comprising the first carrier according to the actual situation. Illustratively, the first carrier may have a plate-like, tubular, or shaped structure as described above, and the carrier portion may include other structures in addition to the first carrier, and in the case where other structures are included, the function, structure, material, and the like of the first carrier and the other structures may be the same or different.

It is understood that a person skilled in the art may determine the graphene heating units included in the graphene heating portion and the specific forms of the graphene heating units according to actual requirements, e.g., in the case where the graphene heating portion includes a plurality of graphene heating units, the structural forms, the arrangement positions, etc. of the plurality of graphene heating units may be the same or different.

The method can be as follows: the through structure on the graphene heating unit positioned on the left side is mainly used for returning air, and the through structure on the graphene heating unit positioned on the right side is mainly used for supplying air; the through structures corresponding to the two graphene heating units comprise a part for returning air and a part for supplying air; in the through structure corresponding to the two graphene heating units, one part is combined into a part for returning air (such as left side is right + right side is left), and the other part is combined into a part for supplying air (such as left side is left + right side is right); etc.

For the above-mentioned partitioned heating type cooking apparatus including graphene, in one possible embodiment, the graphene heating unit includes a plurality of heating portions, and at least some of the plurality of heating portions are disposed in a relatively independent manner.

With this configuration, it is possible to optimize the heating performance of the cooking medium in the cooking chamber by differentially controlling the plurality of heating portions.

For example, the first carrier may include one or more graphene coatings, and the graphene coatings may be coated on a partial or entire region of the layout space.

For the above-mentioned partitioned heating cooking apparatus including graphene, in one possible implementation manner, the carrier portion includes a second carrier, wherein the graphene coating layer is coated on the second carrier, and the first carrier and the second carrier form the layout space.

By means of this construction, a specific design of the carrier part is provided.

As in this case, the second carrier also participates to some extent in the formation of the layout space, so it is understood that the layout space is formed by the first carrier and the second carrier together. Accordingly, a person skilled in the art can determine the structural form of the second carrier and a specific manner of forming the layout space by the first carrier and the second carrier according to actual requirements, for example, when forming the layout space, the second carrier is directly carried on the first carrier, or in order to form an effective layout space, other components besides the first carrier need to be introduced. The second carrier is illustratively snapped into the interior of the arrangement space formed by the first carrier in an embedded manner, the second carrier only allowing the graphene to be applied in its local area. In this case, it is understood that the arrangement space is further limited by the arrangement of the second carrier, and that the arrangement space can be further planned in detail by the arrangement of the second carrier.

For the above-mentioned partitioned heating cooking apparatus comprising graphene, in a possible implementation manner, the first carrier layer and/or the second carrier layer is glass ceramic.

By such a construction, a specific choice of materials for the first carrier layer and the second carrier layer is given.

Referring to fig. 1 to 5, fig. 1 illustrates a schematic structure of an oven according to an embodiment of the present utility model, fig. 2 illustrates a schematic structure of an oven stroke cover assembly according to an embodiment of the present utility model, fig. 3 illustrates a schematic structure of two graphene heating units including a fan cover frame in an oven according to an embodiment of the present utility model, fig. 4 illustrates a schematic structure of a first embodiment of one graphene heating unit disposed inside a bottom portion of a liner in an oven according to an embodiment of the present utility model, and fig. 5 illustrates a schematic structure of a second embodiment of one graphene heating unit disposed inside a bottom portion of a liner in an oven according to an embodiment of the present utility model. As shown in fig. 1 to 5, the oven 100 mainly includes a cooking main body 1, a fan cover assembly 2, and a graphene heating portion, in this embodiment, the graphene heating portion includes three graphene heating units, which are respectively denoted as a first graphene heating unit 3a, a second graphene heating unit 3b, and a third graphene heating unit 3c, where the (first and second) graphene heating units are left and right disposed inside the rear portion of the cooking main body and participate in forming the fan cover assembly together, and the third graphene heating unit is disposed inside the bottom portion of the cooking main body. Wherein the cooking body 1 is formed with a cooking chamber (e.g., a liner) for holding food materials to be cooked. If a shelf is arranged in the inner container, the food materials are directly placed in the shelf or placed in a vessel (such as a disk) placed on the shelf. The fan cover component comprising the (first and second) graphene heating units is mainly used for forming a circulating hot air flow serving as a cooking medium in the inner container, and cooking food materials to be cooked by taking the hot air flow as the cooking medium. The third graphene heating unit is mainly used for further heating hot air flowing into the inner container in the cooking process.

In one possible embodiment, the fan housing assembly 2 mainly includes a fan housing frame 21, graphene heating units (3 a, 3 b) disposed in the fan housing frame, and a fan for implementing hot air flow circulation, and specifically includes: the inner container is provided with a door body near an operation side (e.g., the operation side is a side facing the user, which may be generally referred to as a front side), such as the body is pivotably provided along a front lower edge of the inner container. The inner container is provided with a first backboard 11 (backboard) and a second backboard 12 in turn from front to back on one side far away from the user (such as may be called the rear side), a hot air chamber is formed between the front side of the first backboard 11 and a panel formed by a fan cover frame and (first and second) graphene heating units, through structures 34 are arranged at positions of the (first and second) graphene heating units close to the middle, such as a combination of a plurality of long strip-shaped holes radiating in the circumferential direction on the through structure on the first graphene heating unit 3a on the left side, and a grid hole combination of a disc-shaped structure on the second graphene heating unit 3b on the right side. In the through structure on the left side, the area, close to the radial inner side, in the strip-shaped hole is mainly used for air return, and the area, close to the radial outer side, in the strip-shaped hole is mainly used for air supply. In the right through structure, the grid holes close to the radial inner side are mainly used for air return, and the grid holes close to the radial outer side are mainly used for air supply.

It is obvious that the above-mentioned construction of the through structure and the division of the air return and supply functions corresponding thereto are only exemplary descriptions, and those skilled in the art can flexibly select the specific form of the through structure according to the actual situation and thus construct the air return path and the air supply path corresponding thereto.

Wherein, the fan is disposed in the hot air chamber at a position corresponding to the through structure, the fan includes a motor (not shown) and a fan 222, wherein the fan is located in the hot air chamber (front side of the first back plate), the motor is located at a position of the first back plate corresponding to the hot air chamber (rear side of the first back plate), the motor is fixed on the first back plate through a motor bracket 2211, the motor bracket is simultaneously fixed on the second back plate 12, and the motor is accommodated in an installation space between the first back plate and the second back plate in an assembled state. The motor rotates to drive the fan to rotate at a position facing the return air area, and the rotation of the fan can lead the air in the liner to flow through the return air area and be introduced into the hot air chamber.

After the air flow in the liner is sucked into the hot air chamber through the return air area under the action of the fan, the air flow is heated by the (first and second) graphene heating units so as to be converted into hot air carrying heat, and then the hot air is thrown to the peripheral air supply area and is sent into the liner again. The hot air flow can continuously release the air carrying heat to the surface of the food material to be cooked by circulating in this way, so that the main cooking function is realized. After the hot air flow enters the inner container, the inner container can be further heated through the third graphene heating unit, so that the temperature quality of the hot air flow is optimized. Because the graphene heating units which participate in forming the fan cover assembly comprise two graphene heating units, one graphene heating unit can be in a working state or can heat the hot air flow entering the hot air cavity in a mode of distinguishing heat radiation capacity according to actual requirements.

In one possible embodiment, a plurality of mounting structures 211 may be provided at the outer edge of the fan housing frame 21, thereby fixing the fan housing composed of the fan housing frame and the (first, second) graphene units to the rear inside of the oven. As in the present embodiment, the mounting structure is a mounting piece provided with mounting holes, for example, the fan housing may be fixed to the rear inside of the oven by means of a screw or the like.

The main differences between the third graphene heating unit and the (first and second) graphene heating units described above are: because the (first and second) graphene heating units need to circulate hot air flow, a through structure for air return and air supply is additionally arranged on the (first and second) graphene heating units. The basic structure of the graphene heating unit is described below with the third graphene heating unit (excluding the through structure).

The third graphene heating unit 3c mainly comprises a carrier part, the carrier part comprises a first carrier fixed on the bottom wall of the inner container, the first carrier comprises a first carrier layer 311 and a second carrier layer 312, a layout space is formed between the first carrier layer and the second carrier layer, and the graphene coating 33 is coated on at least one part of the layout space. Because the first carrier is coated with the graphene coating, the arrangement mode of the graphene coating can be flexibly set according to requirements. In this embodiment, the first carrier layer and the second carrier layer are both glass ceramics (the thermal expansion coefficient of the glass ceramics is basically zero, so that the glass ceramics has good high temperature resistance and can cope with the high temperature environment in the liner).

The mode of coating the graphene in the layout space can comprise the following two modes:

1) As shown in fig. 4, in one possible embodiment, the graphene coating 33 is directly applied between the first support layer 311 and the second support layer. For example, the trend of the graphene in the layout space can be limited to a U shape (double-line U shape), an S shape (double-line S shape), a round shape (round-like shape), a square shape (square-like shape) and the like, or large-area spraying can be performed in the layout space. Whether spraying with linear trend or large-area spraying is carried out, a plurality of relatively independent heating parts on electric connection can be formed in the layout area, and therefore diversified heating performance of the graphene heating parts can be achieved through differentiated control of the heating parts. Illustratively, each turn in the circular-like structure is defined as a heating portion.

2) As shown in fig. 5, in one possible embodiment, the carrier part further includes a second carrier 32, for example, the second carrier is a plate-like structure similar to the first/second carrier layer in the first carrier or a flexible film-like structure, and for example, the second carrier is a film-like structure, and for example, first, a coating track is formed on the film-like structure, for example, a U-shaped (double-line U-shaped), an S-shaped (double-line S-shaped), a circular (circle-like) and a square (square-like) blind groove (concave one) can be formed on the coating track, which is a U-shaped blind groove in this example.

On this basis, the following spraying process can be adopted: the graphene coating 33 is coated in the coating track, and then the second carrier 32 containing the graphene coating is pressed between two layers of microcrystalline glass. Or is: firstly, loading a second carrier on one of two layers of microcrystalline glass, then coating a graphene coating 33 in a coating track of the second carrier participating in construction, and finally pressing the second carrier containing the graphene coating and the layer of microcrystalline glass on the other layer of microcrystalline glass.

It can be seen that, in the oven of the present utility model, by the arrangement of the graphene heating portion, the hot air circulating in the inner container can be heated better by means of the good thermal conductivity of graphene, so that the temperature quality of the hot air as a cooking medium is ensured. Under the premise, the specific structural form of the graphene coating can be planned more flexibly according to actual requirements by adopting a structure/process form that the graphene coating is coated on the first/second carrier, so that the problem that the traditional graphene heating pipe cannot process bending can be solved. In addition, by providing a plurality of graphene heating units constituting the graphene heating unit at different positions of the oven, it is possible to ensure the temperature quality of the hot air flow as the cooking medium by means of zone heating.

Thus far, the technical solution of the present utility model has been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of protection of the present utility model is not limited to these specific embodiments. Equivalent modifications and substitutions for related technical features may be made by those skilled in the art without departing from the principles of the present utility model, and such modifications and substitutions will fall within the scope of the present utility model.
